Immunoglobulin isotype switching happens:
WitrynaSomatic hypermutation (SHM) and class switch recombination (CSR) cause distinct genetic alterations at different regions of immunoglobulin genes in B lymphocytes: point mutations in variable regions and large deletions in S regions, respectively. Yet both depend on activation-induced deaminase (AID), the function of which in the two … WitrynaThe levels of surface expression of IgD isotype has been associated with differences in B cell activation status but their role in serum is poorly understood. The IgG, IgE and …

Did you know?
WitrynaImmunoglobulin class switching, also known as isotype switching, isotypic commutation or class-switch recombination , is a biological mechanism that changes … WitrynaSince the discovery that isotype switching is mediated by a somatic rearrangement event, progress in the field of isotype switching has come a long way: switch factor activity for several T-cell-derived cytokines has been discovered. The mechanism of action of these switch factors seems to be relate …
WitrynaSummary. Class-switch recombination (CSR) is a DNA recombination process that replaces the immunoglobulin (Ig) constant region for the isotype that can best protect against the pathogen. Dysregulation of … WitrynaSomatic hypermutation (or SHM) is a cellular mechanism by which the immune system adapts to the new foreign elements that confront it (e.g. microbes), as seen during class switching.A major component of the process of affinity maturation, SHM diversifies B cell receptors used to recognize foreign elements and allows the immune system to adapt …
